People who are familiar with lobe pumps may know that the rotor blades of lobe pumps have single, two, three, four and five leaves, but what are the differences between these leaf types? Here's a breakdown for you.
One lobe: suitable for conveying media containing large particles of material, the crushing rate of large particles of material is low, but its pulsation is large, the pressure is low, and the volume is small.
Second lobe: suitable for conveying media containing small and medium-sized materials, with relatively low crushing rate for small and medium-sized materials, slight pulsation, and larger volume than the one-lobe rotor.
Three-leaf: a general rotor type, the volume is larger than other types of rotors, various performance indicators are better than the one-leaf and two-leaf rotor, three-leaf rotor in the process of conveying materials for granular materials have a certain crushing rate.
Four-leaf: widely used for conveying viscous media, with its small size, strong power, no pollution and other advantages are widely used in food and beverage, chemical, pharmaceutical and other industries .
There are two other special structure rotor lobes in the lobe pump, which are:
1. Butterfly type: Because of the butterfly rotor, it has the general characteristics, in addition to its advantages in conveying high viscosity and materials containing larger particles inside, and it can effectively convey particularly viscous materials.
2. Single butterfly curve type: This series of pumps is specially designed and manufactured to solve the problem of conveying materials containing large particles. Its unique shape and curve form make it incomparable to other pumps when conveying materials containing large particles.
